AXLE-MOUNTING.

SPECIFICATION forming part of Letters Patent No. 432,109, dated July 15, 1890.

Application tiled October 21, 1889. Serial No. 327,609. v (No model.)

To all whom it may concern:

, Be it known that I, MARION A. ANDREWS, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Axle-Mountin gs, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in the mounting of cars upon theiraxle-bearin gs and to the bearings themselves, and which are designed to reduce the friction of the axle in its bearings, and consequently reducing the draft proportionally to the frietional reduction.

The object of my invention is to produce an anti-friction journal-bearing, and also one which requires no oiling, in which a ring bears functionally upon the top of the axle,a grooved roller fitting upon the inner face of the ring vertically opposite the axle, which primarily receives the weight of the car and load and through which and the ring it is transmitted to the axle, and friction-rollers between the grooved roller and inner face of the ring to steady the ring, preventing oscillation, and also aiding in transmitting friction to the ring to rotate it jointly with the friction of the grooved roller, and also providing friction-rollers or other friction mechanism bearing horizontally against the axle opposite each other to steady the axle and prevent it from being thrown out of line horizontally with the oscillation of the car-body or truck.

My invention, being an improvement upon a patent granted to II. L. Phelps June 19, 1888,No. 384,782,0onsists inthe several novel features hereinafter described, and which are set forth in the claims annexed hereto.Y

It is constructed as follows, reference being had to the accompanying drawings, in which y Figure 1 is a rear elevation of the journalbox with the cap removed. Fig. 2 is a rear elevation of the cap, showing the axle in the slot. Fig. 3 is a plan View of the inner face of the cap, showing the axle between the rollers. Fig. 4 is a vertical sectional elevation of Fig. 1. Fig. 5 isa horizontal section of the cap shown in Fig. 2. Fig. 6 is a vertical transverse section of the cap, showing a yielding or springy frictional mechanism to support the sides of the axle against horizontal wabbling. l

A is the journal-bearing mounted in aboxframe in any ordinary way and provided with the side shoulders 1, which support the lower ends of the springs in the usual way.

The bearing consists of a hollow body 2 and a cap or cover 3, closing the open or inner side of the bearing. IVithin this body I place a loose cylindrical ring 4, of smaller external diameter than the bore of the body. A shaft 5 is mounted in the body in substantially a vertical line below the axle 6.

Upon the shaft I mount the roller 7, grooved in its periphery, so as to freely receive the ring between the flanges 8.

Between the roller and the ring, and bearing against both of them, I mount the idler friction-rollers 9 upon shafts mounted in the body, and these rollers, rotating with the grooved roller and ring, aid in the rotation of the ring and support and steady it and maintain it in proper vertical alignment and prevent it from wabbling and twisting.. A

The axle 6 is inserted intothe box through an enlarged opening 10 in the cap or'cover, and the ring 4t lies upon the top thereof and is carried upon the axle and is thus carried by the axle, the grooved roller, and frictionrollers,I and the ring thus constitutes a suspended bearing for the axle Within the box.

In a casing 11 upon the cap I mount the friction-rollers l2 in such a manner that, being in longitudinal and horizontal alignment with the axle, they bear against the opposite sides thereof and operate to steady it against horizontal oscillation through the swinging of the car or truck.

In Fig. 6 I show vertical plates 16, each provided with graphite or other anti-frictional facing 17, which bears against the sides of the axle, and behind these plates I place an elastic cushion of rubber, springs or other material, so that either plate can give a little when the axle bears strongly against it with a sudden lurch of the car. These facings 17 may be concaved to more closely fit the periphery of the axle, if desired. Adjusting set-semi Ys bearing against theplates can also be inserted, if desired, to take up the wear.

Through the front of the body I insert a threaded rod 13, having a squared head 14 IOC) and set-nut external to the body, and upon the inner end I mount a flat disk or roller 18,

of graphite or other anti-friction material,A

the inner face of the ring 4, through the ring upon the idler-rollers 9 and upon the axle 6,

vand that with the rotation of the axle the ring isfrictionally rotated, rotating the grooved roller and the idlers, and that the joint operation of the flanges upon the roller and the graphite disk is manipulated in a vertical position, so that its inner face always remains flat' and true.

What I claim isn *1.* The combination, with the outer end of a caiaxle, 0f a metallic ring larger than the axle andffsuspended thereon, a roller within the ring"` and receiving it between its flanges, and idlers between the roller and ring upon either t side of the axle, as set forth.

roller and the axle on either side, and a disk engaging with the edge of the ring, as set forth. The combination, with the outer end of a cariaxleinserted into the journal-box case, ot'

vafnietallic ring suspended from the axle, a

` grooved roller, and idlers mounted upon separate arbors and bearing with frictional contact 'against the inner surface of the ring and all frictionally rotated by the rotation of the axle, as set forth.

4. The combination, with a car-axle loosely inserted through the journal-case, of frictional supports bearing horizontally against the opposite sides of the axle, a metallic ring suspended from the axle, a grooved roller, and idlers mounted upon separate arbors and bearing with frictional contact against the inner surface of the ring and frictionally rotated by the rotation ofthe axle, as set forth.

5. The combination, with the car-axle loosely inserted through thej ournal-case, of frictional 4supports bearing horizontally against the opposite sides of the axle, a metallic ring suspended from the axle, a grooved roller, and idlers mounted upon separate arbors and bearing with frictional contactagainst the inner surface of the ring and all frictionally rotated by the rotation of the axle, and a disk adjustably mounted in the case and bearing frictionally against the edge of the ring, as set forth.

6. The combination, with a ear-axle loosely inserted through the journal-case, of frictional supports bearing yieldingly and horizontally against the opposite sides of the axle, a metallic ring suspended from the axle, a grooved roller, and idlers mounted upon separate arbors and bearing with frictional contact against the inner surface of the ring and all frictionally rotated by the rotation of the axle, as set forth.

In Witness whereof I have hereunto set my hand this 11th day of October, 1889.
